OBJECTIVE:Eotaxin is a recently characterized chemokine with potent and selective chemotactic activity for eosinophils. Previous studies indicating that eosinophils accumulate and become activated in inflammatory bowel disease (IBD) led us to hypothesize that eotaxin is potentially involved in the pathophysiology of IBD and, therefore, that eotaxin would be(More)
Strongyloides stercoralis infection is characterized by the production of IgE and eosinophils in peripheral blood. Experimental studies have demonstrated that eosinophils play an important role in protection against Strongyloides stercoralis, but the mechanisms regulating eosinophils are not known. In this study we have focused on analysing the molecules(More)
BACKGROUND Allergoids are widely used in specific immunotherapy (SIT) for the treatment of IgE-mediated allergic diseases, but all techniques for standardization of conventional allergic extracts may not be appropriate for standardization of a glutaraldehyde (GA)-modified extract because of the unique characteristics of these extracts. OBJECTIVE To assess(More)
Peripheral T-lymphocytes were analyzed in three groups of people: (1) individuals with current liver hydatid disease (hydatid patients, n = 20), (2) persons who had undergone surgical cyst removal at least 2 years previously (recovered patients, n = 9), and (3) a control group of healthy volunteers (uninfected controls, n = 13). Group 1 was subdivided(More)
BACKGROUND Parietaria pollen is one of the most important causes of pollinosis in Mediterranean countries. Parietaria judaica pollen extract presents two major allergens, Par j 1 and Par j 2, that belong to the lipid transfer protein family. OBJECTIVE To develop an ELISA for quantification of both major allergens of P. judaica pollen extracts, and to(More)
Invasive infections with opportunistic fungi, such as Candida albicans, have become an increasing problem in aged adults in recent years. This work investigates the influence of human ageing on C. albicans recognition by toll-like receptors (TLRs), essential components of the innate immune system, using a cohort of 96 young (15-42 years) and aged (>70(More)
BACKGROUND Despite the use of conventional allergen-specific immunotherapy in clinical practice, more defined, efficient, and safer allergy vaccines are required. OBJECTIVE The aim of the study was to obtain hypoallergenic molecules by deleting B-cell epitopes, which could potentially be applied to Parietaria judaica pollen allergy treatment. METHODS(More)
BACKGROUND The incidence of Human Cytomegalovirus (HCMV) end-organ disease has dramatically decreased since the implementation of highly active antiretroviral therapies (HAARTs), but the precise immune mechanism whereby HCMV is controlled remains to be elucidated. OBJECTIVES To investigate the effect of (HAART) on CD4+ T-cell immunity to HCMV in AIDS(More)
BACKGROUND Platanus acerifolia is an important cause of pollinosis in Western European cities. Pla a 1, a nonglycosylated 18-kDa protein with a prevalence of 80%, is a major allergen in P. acerifolia pollen extracts. Our aim was to develop a Pla a 1-specific ELISA to quantify this protein in allergenic extracts and preparations for clinical use. METHODS(More)
